An embodiment of the present disclosure provides an electronicvaporization device 100. Referring to FIGS. 1-3 , the electronicvaporization device 100 includes a first shell 10, a liquid storage part20 and a second shell 30. The liquid storage part 20 internally has aliquid storage chamber for storing a liquid substrate and an airflowchannel for guiding an air flow. An outer surface of the liquid storagepart 20 includes a first part 210 and a second part 220. A protrusionpart 211 protrudes from the outer surface 210 of the first part or theouter surface 220 of the second part. The first shell 10 covers thefirst part 210 of the outer surface of the liquid storage part 20 and isfixedly connected to the liquid storage part 20. The second shell 30covers the second part 220 of the outer surface of the liquid storagepart 20 and is fixedly connected to the liquid storage part 20.Meanwhile, the protrusion part 211 is at least not covered by the firstshell 10 and the second shell 30. Since the electronic vaporizationdevice 100 is divided into the first shell 10, the liquid storage part20 and the second shell 30. During assembly, only the first shell 10 andthe second shell 30 need to be fixedly connected to the liquid storagepart respectively, thereby facilitating production.

The fixed connection may be detachable connection or non-detachableconnection. In a case of non-detachable connection, when the first shell10 and the second shell 30 are respectively fixedly connected to theliquid storage part 20, the electronic vaporization device 100 can beconstructed as an integrated body. When the user needs to fill theliquid substrate into the liquid storage chamber of the liquid storagepart 20 by himself, the fixed connection can be detachable connection,so that the user conveniently disassembles the first shell 10 or thesecond shell 30 from the liquid storage part 20 and then fill the liquidsubstrate into the liquid storage chamber after the liquid substrate isconsumed up.

In some embodiments, the protrusion part 211 is configured to besubstantially annular. That is, the protrusion part 211 protrudes alongthe outer surface 210 of the first part or the outer surface 220 of thesecond part in a circumferential direction. The protrusion part 211 isconfigured to be substantially annular, which can make the overallappearance of the electronic vaporization device 100 more harmonious andbeautiful.

In some embodiments, the protrusion part 211 is made of a transparentmaterial, so that the airflow channel and the liquid storage chamber inthe liquid storage part 20 can be observed through the protrusion part211 at the same time, which is convenient for the user to observe theremaining liquid volume of the electronic vaporization device 100 andthe smoke volume of the aerosol during inhalation.

In the above embodiment, the protruding height of the protrusion part211 is substantially the same as the shell thicknesses of the firstshell 10 and the second shell 30. When the first shell 10 and the secondshell 30 cover over the liquid storage part 20, the first shell 10 andthe second shell 30 abut against the protrusion part 211 of the liquidstorage part 20 respectively. Since the protruding height of theprotrusion part 21 is substantially the same as the shell thickness ofthe first shell 10 and the second shell 30, after the first shell 10 andthe second shell 30 cover over the liquid storage part 20, the shellsurface of the electronic vaporization device 100 can be made flush, andthe flush surface is beneficial to improving the appearance of theelectronic vaporization device 100.

Certainly, in some other embodiments, the protruding height of theprotrusion part 21 may only be substantially the same as the thicknessof any one of the first shell 10 or the second shell 30 and does notneed to be the same as the thickness of both the first shell 10 and thesecond shell 30.

Further referring to FIGS. 5 and again, FIGS. 5 and 6 respectively showa three-dimensional schematic diagram and a schematic cross-sectionaldiagram of the liquid storage part 20 in a direction. The housing of theliquid storage part 20 has a proximal end 211 and a distal end 212opposite to each other, and both the proximal end 211 and the distal end212 are open. An axially extending chamber structure 22 is arrangedinside the housing, a liquid storage chamber 221 is arranged inside thechamber structure 22 and configured to store a liquid substrate, such asvaporable medicinal liquid or e-cigarette liquid, and the airflowchannel is defined and formed between an outer wall of the chamberstructure 22 and an inner wall of the liquid storage part 20. Aerosolreleased from the electronic vaporization device 100 that vaporizes theliquid substrate can flow to the opening at the proximal end 211 throughthe airflow channel and escape from the liquid storage part 20 throughthe opening at the proximal end 211.

Further, a partition wall 2212 extends radially inside the chamberstructure 22. The partition wall 2212 divides the interior of thechamber structure 22 into a liquid storage chamber 221 and a firstaccommodating chamber 223. The first accommodating chamber 223accommodates a vaporization element 80 of the electronic vaporizationdevice 100. The vaporization element 80 is in fluid communication withthe liquid storage chamber 221, so that the liquid substrate in theliquid storage chamber 221 can flow onto the vaporization element 80 inthe first accommodating chamber 223 for vaporization. Specifically, aliquid guide opening 2213 is formed in the partition wall 2212, and theliquid substrate in the liquid storage chamber 221 can flow to thevaporization element 80 through the liquid guide opening 2213. Theliquid storage chamber 221 and the first accommodating chamber 223 aredistributed on two sides of the liquid guide opening 2213.

In some embodiments, in the case where the chamber structure 22 axiallyextends inside the housing 21, the chamber structure 22 divides theinterior of the housing 21 into a liquid storage chamber 221, a firstchamber 2221 and a second chamber 2222 that are isolated from eachother. The first chamber 2221 and the second chamber 2222 aredistributed on two sides of the liquid storage chamber 221 and aerosolcan flow through the first chamber 2221 and the second chamber 2222respectively. That is, the airflow channel is divided into a firstairflow channel 2221 and a second airflow channel 2222. Preferably, thedimensions of the first airflow channel 2221 and the second airflowchannel 2222 are substantially the same in the same cross section, sothat aerosol can escape from the liquid storage part 20 more smoothly.

Specifically, one set of opposite side walls 222 of the chamberstructure 22 is respectively connected between the opposite inner wallsof the liquid storage part 20, while other side walls of the chamberstructure 22 are directly formed by the inner walls of the liquidstorage part 20, so the interior of the housing 21 is divided into theliquid storage chamber 221, the first chamber 2221 and the secondchamber 2222 by the side walls 222. In other embodiments of the presentdisclosure, there may be a gap between the outer wall of the chamberstructure 22 and the inner wall of the housing 21 in the circumferentialdirection, and the gap may be used to form an airflow channel.

The electronic vaporization device 100 further includes a first sealmember 40 for sealing the liquid storage chamber 221. Further referringto FIGS. 7 and 8 , FIGS. 7 and 8 respectively show three-dimensionalschematic diagrams of the first seal member 40 in two directions. Thefirst seal member 40 is made of a flexible soft rubber material, such assilicone or rubber. The first seal member 40 includes an end surface 41and a side wall 42 extending from the end surface 41 in a direction awayfrom the liquid storage chamber 221. The end surface 41 and the sidewall 42 define and form a second accommodating chamber 43, and thesecond accommodating chamber 43 is configured to hold the vaporizationelement 80 of the electronic vaporization device. A liquid guide hole411 is formed in the end surface 41 and the first seal member 40 isinterference-fitted in the first accommodating chamber 223, so that thefirst seal member 40 elastically abuts against the inner wall of thefirst accommodating chamber 223 and moreover the liquid guide hole 411of the first seal member 40 communicates with the liquid guide opening2213. The liquid substrate in the liquid storage chamber 221 cannot leakthrough an assembly gap between the vaporization element 80 and theinner wall of the second accommodating chamber 223. The first sealmember 40 provides a seal between the vaporization element 80 and theinner wall of the first accommodating chamber 223, and the liquidsubstrate can only flow to the vaporization element 80 in the secondaccommodating chamber 43 through the liquid guide opening 2213 and theliquid guide hole 411.

Further referring to FIG. 9 , the vaporization element 80 includes aporous body 81 and a heating element 82 combined on the porous body 81.The porous body 81 can be made of a hard capillary structure, such asporous ceramics, porous glass ceramics, and porous glass. In theembodiments, the porous body 81 may be generally but not limited to ablock-shaped structure. According to the usage situation, the porousbody 81 includes a liquid absorbing surface 811 and a vaporizationsurface 812 oppositely arranged along the axial direction of theelectronic vaporization device 100, i.e., upper and lower surfaces ofthe block-shaped porous body 81 shown in FIG. 8 . The liquid absorbingsurface 811 is configured to absorb the liquid substrate, and theheating element 82 is combined with the vaporization surface 812 to heatthe vaporized liquid substrate. The porous body 81 is at least partiallyaccommodated in the second accommodating chamber 43. Since the firstseal member 40 is made of a flexible material, the porous body 80 can betightly fitted in the second accommodating chamber 43 through aninterference fit. In this case, the liquid absorbing surface 811 of theporous body 81 is accommodated in the second accommodating chamber 43and faces the liquid guide hole 411 of the first seal member 40, so thatthe liquid substrate can flow to the liquid absorbing surface 811through the liquid guide hole 411 and further flow to the vaporizationsurface 812 through the internal microporous structure of the porousbody 81.

The heating element 82 is preferably formed on the vaporization surface812 by mixing conductive raw material powder with a printing assistantto form a slurry and then sintering after printing according to a properpattern, so that an entire surface or most of the surface of the heatingelement is closely attached to the vaporization surface 812, and theheating element has effects such as high vaporization efficiency, lessheat loss, and dry-burn prevention or dry-burn reduction. In someembodiments, the heating element 82 may be in a variety of structuralforms. The heating element 82 may be a sheet-shaped heating body, or inother forms such as a heating mesh, a disc-shaped heating body formed bya spiral heating wire, or a heating film, that is combined with thevaporization surface 812 and has a specific pattern. For example. thespecific pattern may be a serpentine shape. In some embodiments, theheating element 82 may be made from a material such as stainless steel,nickel chromium alloy, iron chromium aluminum alloy, or metal titanium.Therefore, when the liquid substrate flows onto the vaporization surface812, the heating element 82 on the vaporization surface 812 can heat andvaporize the liquid substrate, and release the aerosol generated aftervaporization from the vaporization surface 812.

Further, the chamber structure 22 is further provided with a liquidfilling opening end 2211 for filling liquid. Before the first shell 10and the liquid storage part 30 are connected, the liquid substrate canbe filled into the liquid storage chamber 221 through the liquid fillingopening end 2211 in advance. After the liquid substrate is filled, thefirst shell 10 is fixedly connected to the liquid storage part 30.

Further, in order to prevent the liquid substrate from leaking from theabove-mentioned liquid filling opening end 2211 when the electronicvaporization device 100 is turned upside down, the electronicvaporization device 100 further includes a second seal member 50. FIGS.and 11 respectively show three-dimensional schematic diagrams of thesecond seal member 50 in two directions. The second seal member 50 isalso made of a flexible soft rubber material such as silicone or rubber.The second seal member 50 has an upper surface 51 and a lower surface 52opposite to each other, as well as a side wall extending between theupper surface 51 and the lower surface 52. A plurality of protrusions511 axially extend from the upper surface 51 toward the first shell 10,and the plurality of protrusions 511 form a clamping space 512. A firstinsertion part 521 axially extends from the lower surface 52 toward theliquid storage part 20, and a rib 5211 is arranged around the outer wallof the first insertion part 521. The first insertion part 521 isinserted into the liquid storage chamber 221 through the opening end2211 of the liquid storage chamber 251. Moreover, the cross-sectionalshape of the first insertion part 521 is adapted to the opening shape ofthe opening end 2211 of the liquid storage chamber 221, so the firstinsertion part 521 can be tightly fitted to the end wall of the openingend 2211 through an interference fit, thereby blocking the opening end2211 of the liquid storage chamber 221 and preventing the liquidsubstrate from flowing out of the opening end 2211 of the liquid storagechamber 221 when the vaporizer 100 is turned upside down. Moreover, inorder to prevent the first seal member from falling into the liquidstorage chamber 221 due to the bumping of the electronic vaporizationdevice 100 during transportation, the cross-sectional area of the firstinsertion part 521 is smaller than the area of the lower surface 52, sothat a part of the lower surface 52 abuts against the end surface of theopening end 2211 of the liquid storage chamber 221, thereby preventingthe first seal member 40 from falling into the liquid storage chamber221.

Further referring to FIG. 12 , FIG. 12 shows a schematic cross-sectionaldiagram of the first shell 10 in a direction. One end of the first shell10 is provided with an air outlet hole 12, through which the aerosolgenerated by vaporization can escape from the vaporizer 100, and theuser can inhale the aerosol at the air outlet hole 12. The other endopposite to the air outlet hole 12 is configured as an open end 13, andthe proximal end 211 of the liquid storage part 20 extends into thefirst shell 10 through the open end 13. The first shell 10 is hollow sothat the aerosol generated by the vaporization element 80 can flow tothe proximal end 211 of the liquid storage part 20 through the firstairflow channel 2221 and the second airflow channel 2222, and furtherenter the interior of the first shell 10 through the opening of theproximal end 211, and then be discharged from the air outlet hole 12 ofthe first shell 10.

The first shell 10 is internally provided with a clamping part 14 thatcan be partially clamped in the clamping space 512. The clamping part 14is formed by extending the inner wall of the first shell 10. Theclamping part 14 has a second insertion part 141 extending axiallytoward the open end 13 of the first shell 10. A second through hole 53axially penetrating through the body of the second seal member 50 isalso formed in the second seal member 50. When the first shell 10 isengaged with the liquid storage part 20, the clamping part 14 is clampedin the clamping space 512 and the second insertion part 141 is insertedinto the second through hole 53 at the same time. It is easy tounderstand that the cross-sectional shape of the second insertion part141 is adapted to the shape of the second through hole 53 so that thesecond insertion part 141 and the second through hole 53 achieve aninterference fit, and the second insertion part 141 can be tightlyfitted to the hole wall of the second through hole 53 in acircumferential direction, thereby sealing the second through hole 53and preventing the liquid substrate in the liquid storage chamber 221from leaking through the second through hole 53 when the electronicvaporization device 100 is turned upside down.

In this embodiment, forming the second through hole 53 in the secondseal member 50 is to discharge part of the air out of the liquid storagechamber 221 through the second through hole 53 when the second sealmember 50 is inserted into the liquid storage chamber 221. Specifically,in actual production and assembly, the liquid substrate is filled intothe liquid storage chamber 221 in advance, and then the second sealmember 50 is installed at the opening end 2211 of the liquid storagechamber 221. In this case, with the insertion of the second seal member50, the air in the liquid storage chamber 221 is compressed, and part ofthe air is discharged from the second through hole 53. Then, the firstshell 10 is assembled on the liquid storage part 20, and at the sametime, the second insertion part 141 of the first shell 10 is insertedinto the second through hole 53. In this case, although the air in theliquid storage chamber 251 will also be compressed with the insertion ofthe second insertion part 141, part of the air is already dischargedfrom the second through hole 53, and only a small amount of air in theliquid storage chamber 221 compresses the liquid substrate. The liquidsubstrate will not flow too much to the vaporization element 80 underthe action of a small amount of air pressure to cause leakage. However,if the second through hole 53 is not formed in the second seal member 50and the second seal member 50 is a completely closed seal member, as thesecond seal member 50 is inserted into the liquid storage chamber 221,the air in the liquid storage chamber 221 is compressed and cannot bedischarged, the compressed air will squeeze the liquid substrate, andtoo much liquid substrate will flow to the vaporization element 80 underthe action of the relatively large gas pressure, thus easily causingleakage.

Further, When the second insertion part 141 is inserted into the secondthrough hole 53, the second seal member 50 may sag under the extrusionforce of the second insertion part 141, thereby causing a gap betweenthe second seal member 50 and the inner wall of the liquid storagechamber 221 and affecting the sealing performance of the second sealmember 50. In order to avoid this problem, the second seal member 50 isprovided with the above-mentioned protrusions 511. When the first shell10 is engaged with the liquid storage part 20, the clamping part 14 ofthe first shell 10 is located in the clamping space 512 of the secondseal member 50, the protrusions 511 clamp the clamping part 14 to reducethe extrusion force exerted by the second insertion part 141 on thesecond seal member 50, thereby effectively preventing the second sealmember 50 from sagging under the extrusion force.

In some embodiments, the first airflow channel 2221 and the secondairflow channel 2222 have a first air outlet port 22211 and a second airoutlet port 22221 through which aerosol escapes from the liquid storagepart 20, as shown in FIG. 5 . The heights of the first air outlet port22211 and the second air outlet port 22221 are both less than the heightof the liquid filling opening end 2211, so that the volume of the liquidstorage chamber 221 can be increased, thereby increasing the liquidvolume of the liquid substrate that can be stored.

Further, the electronic vaporization device 100 further includes aventilation channel for communicating with the external air and theliquid storage chamber 221 to guide the external air into the liquidstorage chamber 221, thereby preventing the generation of negativepressure in the liquid storage chamber 221 with the consumption of theliquid substrate and further preventing the vaporization element 80 fromdry burning which occurs if the liquid substrate cannot flow smoothly tothe vaporization element 80 under the action of negative pressure. Theventilation channel has an air inlet and an air outlet, and external airenters into the ventilation channel through the air inlet and escapesfrom the air outlet in the form of air bubbles. The first seal member 40has an air bubble guide part 412 extending toward the liquid storagechamber 221. The air bubble guide part 412 is arranged opposite to theair outlet of the ventilation channel. The air bubble guide part 412 isconfigured to guide into the liquid storage chamber 221 the air bubblesescaping from the air outlet of the ventilation channel when theelectronic vaporization device 100 conducts ventilation, that is, toguide the air bubbles away from the liquid absorbing surface 811 of thevaporization element 80. In this way, the air bubbles escaping from theair outlet of the ventilation channel can be prevented from accumulatingon the liquid absorbing surface 811 and blocking the liquid guideopening 2213 and thus the vaporization element 80 can be prevented fromdry burning which occurs if the liquid substrate in the liquid storagechamber 221 fails to flow smoothly to the vaporization element 80.

In some embodiments, as shown in FIG. 13 , FIG. 13 shows a schematiccross-sectional diagram of the liquid storage part 20 in a direction. Agroove 2231 is formed in the inner wall of the first accommodatingchamber 223. The groove 2231 includes a first part 22311 and a secondpart 22312 communicating with the first part 22311. The first part 22311is formed on the side wall of the first accommodating chamber 223. Thesecond part 22312 is formed on the partition wall 2212, passes throughthe hole wall of the liquid guide opening 2213 of the partition wall2212, and then communicates with the liquid storage chamber 221. Thesecond part 22312 extends non-linearly, thereby increasing the length ofthe airflow path, which is beneficial for alleviating or preventing theliquid substrate in the liquid storage chamber 221 from leaking from thegroove 2231. For example, in some examples, the second part 22312extends in an L shape, a zigzag shape or an S shape. When the first sealmember 40 is installed in the first accommodating chamber 223, thesurface of the first seal member 40 elastically abuts against the innerwall of the first accommodating chamber 223, and then the first sealmember 40 and the groove 2231 define and form a ventilation channel, andexternal air enters the ventilation channel through the first part 22311and escapes from the second part 22312 in the form of air bubbles.

The first seal member 40 is provided with the above-mentioned air bubbleguide part 412. Specifically, the air bubble guide part 412 isconfigured as a flat plate and has a blocking plane 4121 for blockingair bubbles from flowing along the liquid absorbing surface 811. Theblocking plane 4121 extends toward the liquid storage chamber 221 in anaxial direction and is arranged opposite to an air bubble air outlet22313. Since the blocking plane 4121 is wider than the air outlet 22313of the ventilation channel, after the air bubbles escape from the airoutlet 22313, under the blocking action of the blocking plane 4121, theair bubbles can only move along the axial direction of the blockingplane 4121 and the air bubbles are guided into the liquid storagechamber 221. That is, the air bubbles are guided away from the liquidabsorbing surface 811, thereby preventing the air bubbles fromaccumulating on the liquid absorbing surface 811 (see the schematicpartial enlarged diagram shown in FIG. 14 ). It is easy to understandthat in other embodiments of the present disclosure, the air bubbleguide part 412 may not be configured as a flat plate as long as the airbubble guide part 412 has the blocking plane 4121 for blocking airbubbles.

In some embodiments, further referring to FIGS. 18 and 19 , the innerwall of the second accommodating chamber 43 a of the first seal member40 a is provided with a groove 431 a. The groove 431 a includes a firstpart 4311 a and a second part 4312 a communicating with the first part4311 a. The first part 4311 a is formed on the side wall of the secondaccommodating chamber 43 a, and the second part 4312 a is formed on thebottom wall of the second accommodating chamber 43 a. When the porousbody 81 of the vaporization element 80 is tightly fitted in the secondaccommodating chamber 43 a, the above-mentioned ventilation channel canbe defined and formed between the porous body 81 and the groove 431 a.External air enters the ventilation channel through an air inlet 43111of the first part 4311 a and escapes from the ventilation channelthrough an air outlet 43121 a of the second part 4312 a. In this case,the second part 4312 a is spaced a certain distance from the hole wallof a liquid guide hole 411 a, that is, the second part 4312 a does notcommunicate with the liquid guide hole 411 a of the first seal member 40a.

The air bubble guide part 412 a is configured in a cylindrical shape,which extends toward the liquid storage chamber in an axial direction.The air bubble guide part 412 a is provided with an air guide channel4121 a axially penetrating through the body of the air bubble guidepart. Functioning as an air channel, the air guide channel 4121 acommunicates with the air outlet port 43121 a of the ventilationchannel. In this way, when the electronic vaporization device 100conducts ventilation, the air can enter the air guide channel 4121 aafter escaping from the air outlet port 43121 a of the ventilationchannel, and then flow along the air guide channel 4121 a to the liquidstorage chamber. The air that escaping from the air guide channel 4121 ais finally released into the liquid storage chamber in the form of airbubbles, thereby achieving the effect of guiding the air bubbles awayfrom the liquid absorbing surface 811.

In some embodiments, further referring to FIGS. 20 and 21 , the groove431 b is also formed on the inner wall of the second accommodatingchamber 43 b of the first seal member 40 b. The groove 431 b alsoincludes a first part 4311 b and a second part 4312 b communicating withthe first part 4311 b, the first part 4311 b is formed on the side wallof the second accommodating chamber 43 a, and the second part 4312 b isformed on the bottom wall of the second accommodating chamber 43 b.Unlike the above embodiment, the second part 4312 b communicates withthe liquid guide hole 411 b of the first seal member 40 b. That is, thesecond part 4312 b extends to the hole wall of the liquid guide hole 411b. The air bubble guide part 412 b extends toward the liquid storagechamber in an axial direction. An air guide groove 4121 b, functioningas an air guide channel, is formed in the surface of the air bubbleguide part 412 b. The air guide groove 4121 b communicates with the airoutlet port 43121 b of the ventilation channel. Air bubbles can enterthe air guide groove 4121 b after escaping from the air outlet port43121 b of the ventilation channel, and enter the liquid storage chamberalong the air guide groove 4121 b, thereby guiding the air bubbles awayfrom the liquid absorbing surface 811. In order to improve the rigidityof the air bubble guide part 412, the air bubble guide part 412 in theall above embodiments can be combined with the hole wall of the liquidguide hole 411.

In other embodiments of the present disclosure, the air bubble guidepart 412 may not be arranged on the first seal member 40. For example,as shown in FIG. 15 , the bubble guide part 412 may be formed from thechamber structure 22. Specifically, the chamber structure 22 is providedwith a partition plate 224 longitudinally penetrating through the liquidguide opening 2213 and the liquid guide hole 411 and extending to theliquid absorbing surface 811, and two ends of the partition plate areconnected to the walls of the liquid guide opening 2213. In this way,the liquid guide opening 2213 is divided into a first part and a secondpart which are isolated from each other, i.e., two liquid outlets whichare isolated from each other. After air bubbles escape from the airoutlet port of the ventilation channel, the partition plate 224 canblock the flow of the air bubbles along the extending direction of theliquid absorbing surface 811 and guide the air bubbles to flow towardthe liquid storage chamber 221 along the longitudinal extendingdirection of the partition plate 224, thereby guiding the air bubblesaway from the liquid absorbing surface 811.

In some embodiments, the electronic vaporization device 100 furtherincludes a bracket Further referring to FIGS. 16 and 17 , FIGS. 16 and17 show three-dimensional schematic diagrams of the bracket 60 in twodirections. The bracket 60 extends in the second shell 30 along an axialdirection and has opposite proximal and distal ends. The proximal endextends into the liquid storage part 20 through the distal opening ofthe liquid storage part 20 and is fixedly connected with the liquidstorage part 20. The bracket 60 is provided with a first installationchamber 611 and a second installation chamber 612, the firstinstallation chamber 611 is configured to install the battery cell 61,and the second installation chamber 612 is configured to install an airpressure sensor 62. The electronic vaporization device 100 furtherincludes a main board (not shown) arranged in the second shell 30, theair pressure sensor 62 and the battery cell 61 are both electricallyconnected to the main board. In order to save manufacturing costs, aplurality of notches 613 are formed in the shell of the bracket 60.

The proximal end of the bracket 60 is provided with a first vent hole65, a second vent hole 66 and a first electrode hole 67. The distal endof the bracket 60 is provided with an air inlet hole 68 for external airto enter the electronic vaporization device 100. After entering theelectronic vaporization device through the air inlet hole 68, theexternal air enters the liquid storage part 20 through the first venthole 65. The second vent hole 66 communicates with the secondinstallation chamber 612 for triggering the air pressure sensor 62 inthe second installation chamber 612. A trigger air channel 6121communicating with the second vent hole 66 is formed in the secondinstallation chamber 612. In order to reduce the noise duringinhalation, two first vent holes 65 are provided, and the two first ventholes 65 are distributed on two sides of the second vent hole 66, andthe two first through holes 65 both have a diameter of 0.6-0.8 mm. Inother embodiments of the present disclosure, there may also be one firstvent hole 65. Compared with the arrangement of two first vent holes 65,the arrangement of one first vent hole can provide a large diameter andit is easy to make noise during inhalation. If two or more vent holesare provided, the diameter of the first vent holes may be made smaller,thereby alleviating the noise generated during inhalation.

The electronic vaporization device 100 further includes a conductiveterminal 64 electrically connected to the battery cell 61. Theconductive terminal 64 extends into the first electrode hole 67. Theconductive terminal 64 is electrically connected to a conductiveelectrode 83 of the vaporization element 80, so that the battery cell 61provides electric energy to the heating element 821 of the vaporizationelement 80. The air pressure sensor 62 is configured to sense the airpressure change during the inhalation of the user and send a sensingsignal to the main board, and the main board controls the battery cellto provide electric energy to the vaporization element 80 according tothe air pressure change.

Further, the electronic vaporization device 100 further includes a thirdseal member 90 which is made of flexible silicone or rubber. The thirdseal member 90 is fitted over the proximal end of the bracket 60 and ininterference fit with the inner wall of the liquid storage part 20,thereby sealing the assembly gap between the bracket 60 and the liquidstorage part 20. There is a gap between the first seal member 90 and thevaporization surface 82 of the vaporization element 80, and the gap isconfigured to form the vaporization chamber 84 of the electronicvaporization device 100. The aerosol generated by heating the liquidsubstrate by the vaporization element 80 is released here in this gapand escapes from the liquid storage part 20 through the above-mentionedfirst airflow channel 2221 and second airflow channel 2222, then entersthe first shell 10, and finally escapes from the electronic vaporizationdevice 100 through the air outlet hole 12 of the first shell 10. It iseasy to understand that the first seal member 90 is provided with asecond electrode hole (not shown) and a third vent hole 91. Theconductive electrode 83 of the vaporization element 80 extends into thefirst electrode hole 67 through the second electrode hole, so as to beelectrically connected with the conductive terminal 64. The first venthole 65 communicates with the third vent hole 91. After escaping fromthe first vent hole 65, the external air enters the vaporization chamber84 through the third vent hole 91, and then flows to the air outlet hole12 through the first airflow channel 2221 and the second airflow channel2222, see the air flow path shown by the arrow route R1 in FIG. 3 . Thethird vent hole 91 is opposite to the second vent hole 66, so that theair pressure sensor can be triggered better. When the user inhales, thesecond installation chamber 612 generates a negative pressure, and theair pressure sensor 62 can sense the air pressure change in the secondinstallation chamber 612, and then generate an induction signal, andsend the induction signal to the main board. The main board thencontrols the electronic vaporization device 100 to work.
